lr-pcsx-rearmed kicks me back to the menu on pi zero with dpi screen, boots games fine on raspberry pi 3 with hdmi on a fresh build

stinus77

@dankcushions actualy the psx can handle 640x480 just not many games use it.
so i made another vidoe showing that i set it to 640x480 that games boot fine on this resolution and don't boot in the sdtv mode.
yes i used the pi3 because that is the only one giving me the 640x480 option wich is not present on th pi zero when i boot it, hence my question is it possible to override the autodetect ? ok, didnt quite put it like that , please understand that its hard for me using another language.

mitu

You can override the detection by using some parameters in the config.txt file on the boot partition of the SD card, see https://www.raspberrypi.org/documentation/configuration/config-txt/video.md.
Are you saying that the PI3 can do 640x480 with the same display, while the Pi Zero cannot ?

stinus77

@mitu no, its a different display. one is on hdmi the other isnt, so it had other resolution options. i am currently testing another pi zero trough hdmi connection, if i get it to work it could be easier to just switch the screens but i would neet to trim 2mm of the board on the back of the screen and don't want to do this to be honest...
i will look in to this option to, thanks

But are you sure your display supports 640x480 over composite ? Do you have a model or a tech sheet to check ?

stinus77

@mitu ive had this diplay lying around for about a year as i ordered it in double as a replacement screen for my sega nomad , so it would take me some time to search again ( but i will do )
the thing is that the gpi case has a display of 320x240 running playstation fine, so i think this should be possible to.
i will get back to you on this.
can i give the playstation emulator settings for other resolutions maybe ?
as mentioned aboveby dankcushions most games run in 320x240, maybe the emulator is based on the 640x480 resolution and a simple fix would geive me custom resolution settings? just thinking, dunno whats possible, so don't shoot me ...

stinus77

@mitu i am totaly lost with the link you sent, any tips of wich i should try, to be honest its a little to technical for me to understand all.
sorry and thank you for the effort you already provided.
btw, i set the screen resolution in the config to 640x480 and the display output is fine, little smaller to read, but working.

If you managed to set the resolution through the configuration utility (raspi-config), then you don't need to modify the file I mentioned - it basically does the same thing.

Try running the emulator without any video settings and see if it works this way.

@mitu ok i didnt set it trough raspi config, did it in on the sd card with the config on that. now did it with raspi config and get no picture only sound.
so this pretty much says i can't do 640x480 , i think . but its progress.
at this moment, what would be the wisest thing to do, should i search another display or do i have other possibility's?
this is progress in my eyes and i am determant to finish this build, so, bare with me on this if you will...
sorry again and a big thank you for sticking with me on this.
can i revert back without having to reflash the image for the time being as i search for another display ?
and how do i start without video settings please?

mitu

@stinus77 remove the video settings from the config.txt file - or revert to the values you had before so you get back the video.
If you don't want to go the HDMI route - which I think would be better, since the composite port is not that great for a small display - then try to run the emulator without any video settings. For a PI Zero, the pcsx_rearmed emulator is the recommended version for PS1, so I'd focus on getting that working.

stinus77

@mitu i'm gonna 3d print this link text and use the hdmi screen in the gameboy. its the same screen i am using ... it should fit with that bracket.
then i need to configure my usb d-link wifi adapter to work on the zero, i am failing miserable at that.
i got the picture back and all is back as it was, deleting the video settings it wasnt booting at all.
i'm gonna make the 2 above my priority so off to my 3d printer... to be continued.

stinus77

so i'm about to give up on this thing, i will make this a emu system untill the psx and build my atari linx project with a raspberry 3 i think.
i don't have the knowledge to finish the build, big bummer i think, but life goes on.
for the life of me i can't get any video out of the pi zero not on the hdmi screen, not on the sd screen, notn much to find in online help either.
as soon as i go on the pi zero nothing works, no rearmed no lr rearmed , no hdmi screen, no sd.
i think after 3 weeks i will go bang my wife again.
thanks for all the help guys.
maybe i will try a few suggestions, but they would have to be good, but now time to rest.

stinus77

so its official, i'm quiting this build.
looking forward to future projects and hoping a pi zero 2 will come along.
i just wanted to take the time to thank everyone here for the effort to make all these projects possible for us, you are doing a great job and i am very greatfull for that.
already have a pi4 at at hand with 4gb and waiting for dreamcast emulation as i see the promising flycast core inplimentation,thats my all time favorite console looking to be very well emulated.
so big thanks to all and let me know if i can donate without paypal, cause i really don't like paypal.
